FunctionFunction

Plectin, a universal and functionally versatile cytolinker protein, can be divided in three main sections; a central coiled-coil rod domain (residues 1492-1530), N and C-terminal globular region and exhibits a dumbbell like structure [1]. C-terminal region is composed of 6 homologous repeating domains (repeat#6 contains residues 4403-4606), and this region has a role in binding to intermediate filaments such as vimentin and cytokeratin[2], [3]. N-terminal globular region contains actin binding domain (ABD) (residues 175-400) comprising of two calponin homology (CH) domains, plakin domain (residues 300-1372) and N-terminal arm, which varies among isoforms.

Mutations in plectin result in skin fragility and blister formation[4].
